HiDew

What HiDew does

HiDew S.r.l. is an Italian manufacturer of industrial dehumidification and ventilation equipment, founded in 2011 and headquartered in Conselve (Padova) with a registered office in Tribano. The company operates as a subsidiary within Gruppo Galletti, with HiRef S.p.A. identified as the controlling parent entity. HiDew designs and produces a portfolio spanning over 25 product SKUs organized into four main lines: swimming pool dehumidifiers (compact residential units through large public and Olympic-pool installations), residential radiant-system dehumidifiers, industrial/service-sector dehumidifiers for 24/7 high-latent-load environments, and high-efficiency heat recovery units for controlled mechanical ventilation. Core technical differentiators include polypropylene housing construction for chlorine-rich corrosion resistance, cross-flow and counter-current heat recovery with efficiencies of 80-90%+, eco-friendly R290 refrigerant adoption, EC inverter fans, and Modbus RS485 connectivity with home automation integration. ISO 9001:2015, ISO 14001:2015, and ISO 45001:2018 certifications support B2B procurement eligibility.

The business model is project-based B2B hardware sales with quote-based pricing and no public e-commerce channel. HiDew serves four primary use-case segments — swimming pools (primary), residential radiant systems (primary), industrial/service (primary), and wine industry (secondary) — through direct enterprise sales and distribution leverage from the Galletti Group network. Geographies served include Italy as the home base, with international reference projects in Qatar (Al Ruwais Pool) and Algeria (Olympic Pool Annaba), and active trade show presence at MCE Milan, ISH Frankfurt, GreenTech Amsterdam, ForumPiscine, and Pool & Fitness Contact. Marketing is executed through trade shows, industry publications (Italian Pool Technology, HA Pool Construction, I Grandi Vini), a bilingual website with reserved technical download portal, and the personalized My HiDew customer portal. Recent strategic moves include ISO 14001/45001 certifications (January 2025), DPS compact dehumidifier launch (March 2025), 120 kW photovoltaic installation (September 2025), and first-time GreenTech Amsterdam 2026 exhibition. Headcount is in the 11-50 band; revenue is not publicly disclosed.

Direct peers

• Munters: Global leader in industrial and commercial dehumidification, including dedicated pool dehumidification systems. Directly comparable as a B2B manufacturer of dehumidification equipment for pools, industrial processes, and climate-controlled facilities, but at significantly larger scale.
• Dantherm Group: European manufacturer of mobile and stationary dehumidification, heating, and cooling solutions for industry, construction, and pool/leisure segments. Overlaps with HiDew in industrial dehumidification and pool climate control.
• Seibu Giken DST: Swedish-Japanese manufacturer of desiccant dehumidification rotors and systems. Comparable as a specialist dehumidification equipment maker serving industrial and commercial applications globally.
• Cotes: Danish manufacturer of adsorption and refrigeration-based dehumidification systems for industrial and commercial use. Comparable as a European specialist in custom-engineered dehumidification solutions.
• Calorex: UK-based manufacturer specializing in dehumidifiers for swimming pools, commercial buildings, and industrial applications. Closest direct competitor in pool dehumidification, with comparable product positioning and B2B distribution.
• PoolPak: US-based manufacturer of commercial pool dehumidification systems. Closely comparable product category (pool dehumidification) with overlapping B2B sales motion through engineers and contractors.

Broad incumbents

• Daikin: Global HVAC leader with a broad portfolio including dehumidification, heat recovery ventilation, and radiant systems. Comparable in product category but vastly larger in scale, R&D, and global reach; represents a competitive threat across all HiDew segments.
• Mitsubishi Electric Hydronics & IT Cooling Systems (Trane): European HVAC OEM with broad coverage of chillers, heat pumps, and air-handling units including humidity control. Competes in the same commercial and industrial customer base as HiDew via specification channels.
• Galletti Group (Gruppo Galletti): Italian HVAC conglomerate that is HiDew's parent and distribution partner. Broadly comparable as an HVAC equipment manufacturer (heat pumps, chillers, terminal units) sharing distribution with HiDew, but operating across a much wider product portfolio.

Emerging players

• Siber Ventilation: Spanish/European manufacturer of mechanical ventilation with heat recovery units for residential and small commercial buildings. Closely comparable in ERV/HRV product category and target market, particularly relevant as HiDew expands into passive-house and hospitality ventilation.
